Referring to the' form shown in Figs. 4

The invention will be best understood by and 5, the printing is applied to the edge surreference to the accompanying drawings, face l5 of asheet of transparent paper 16,' forming a part of this specification, and in after which the sheet may be rolled to the 5o which: form shown, and because of therelatively 100 large surface covered by the ink 17, additional application of adhesive is rendered unnecessar If desired, glue or other eXtraneous a hesive may be added to the ink for printing purposes to increase the adhesive properties of the ink, although in many cases the usual printing ink will cause the contacting surfaces to tightly adhere, particularly where a thin, plia le paper is used. As indicated, after the roll is completed, the printed subject matter is clearly visible from the reverse side of the sheet from that upon which the printing has been applied, and in these two adaptations described a direct reading plate or setting of type is used. It will be understood, however, that the printing may be applied, if preferred, to the covered surface, inasmuch as the outline will be clearly visible throu h the coverin sheet. In the form shown in 4igs. 6 and 7, ecause of the relatively small area covered by the ink, an additional adhesive 18 is applied along the margin of the overlapping portion. In the adaptation of the method shown in Figs. 8, 9 and 10, a marginalportion 19 of a sheet of transparent paper 2O receives t-he rinting and the marginal paper is then folded to the position shown in Fig. 9, with the printed outline visible from the exterior through the folded marginal portion 19. The method permits of employment in the application of printing to transparent paper for any desired purpose, and the paper is available for use immediately upon completion of the operations of the method, whereas the time consumed and expense involved in the previous methods have been so great that printing has not been applied to the character of paper disclosed except in rare instances.

It is obvious from the foregoing that the method above described is equally applicable to sheets which are not totally transparent, but are more nearly translucent; also to sheets which are not commonly designated as paper, such as cellophane and the like.

While I have illustrated and described the preferred method for carrying my invention into effect, this is capable of variation and modification without. departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of method steps set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

1. The method of applying printed matter to a substantially transp arent sheet which comprises printing with adhesive ink upon a receiving surface and then placing said transparent sheet over the freshly printed surface to cause said surface and sheet to adhere by reason of the adhesive properties of the ink used in the printing.

2. The method of applying printed matter to ra substantially transparent sheet which comprlses printing with adhesive ink upon a portion of a receiving surface, appl ing adhesive to another portion of sald sur ace, and then placing said transparent sheet over the freshly printed surface to cause the surface and sheet to adhere by virtue of the united properties of the ink and adhesive.

3. The method of applying printed matter to a substantially transparent sheet which comprises printing with adhesive ink upon another substantially transparent sheet, and placing said first sheet over the freshly printed surface of the second to cause both of said sheets to adhere by reason of the adhesive properties of the ink used in the printing.

4. The method of applying printed matter to a substantially transparent sheet which comprises printing with adhesive ink upon a portion thereof, and then placing a second portion of the sheet over the first freshly printed surface of the portion to unite the portions by reason of the adhesive properties of the ink used in the printing.

5. The method of applying printed matter to a substantially transparent sheet which comprises printing with adhesive ink upon one side of the sheet, and folding said sheet to bring the printed surface into contact with a remaining portion of the sheet, whereby the contacting portion of the sheet will be caused to adhere and the printed matter disposed between the portions, by reason of the adhesive properties of the ink.

6. The method of applying printed matter to a substantially transparent sheet which comprises printing invertedly with adhesive ink upon a portion of the sheet, and folding said printed surface into contact with a remaining portion to cause the portions to adhere by reason of the adhesive properties of the ink.

7 The method of applying printed mattei' to a substantially transparent sheet which comprises printing with adhesive ink upon a portion thereof, applying adhesive to said portion, and causing a second portion of the sheet to be united to the printed surface by virtue of the united properties of the ink and adhesive.

In testimony whereof I have signed my name to this specification.
